Specification of Letters Patent.

Patented Mar.4, 1919.

Application filed March 1, 1918. Serial No.-219,920.

To all whom it may concern Be it known that I, SIMON H. FETHER, a citizen of the United States, residing at Archbold, in the county State of Ohio, have invented certain new and useful Improvements in Hot-Box Detectors for Railway-Cars, of which the following is a specification. A

This invention relates to new and useful improvements in hot box or hot journal detectors for railway passenger cars, and the primary object of the invention is to provide a device to detect overheated journals or hot boxes from the inside of the cars while the car is in motion.

Another object of the invention is to provide a device of this character which is adapted to be so arranged that it is normally inoperative, but is adapted to be moved to operative position from the railway cars, so that the journal or hot box may be easily tested to determine if the same is overheated.

A further object of the invention is to provide a device of this character which is easily and simply constructed, inexpensive to manufacture, and one which will be very efiicient in operation.

With these and numerous other objects in view, my invention consists of thenovel features of construction, combination and arrangement of parts which will be herein referred to and more particularly pointed out in the specification andclaims.

In the accompanying drawings:

Figure 1 is a vertical section throughthe device, and

Fig. 2 iS a removed.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The numeral 1 designates a tubular mem-v ber which extends up through one sideof a railway car, within the car and its upper end is provided top plan view with the cover with a head portion 2 secured thereon and adapted to open through the window sill of the car. A hinged closure 3 is provided at the upper end of the head, and said head is provided with interior shoulder portions 4: which are provided with V 7 opposed recesses therein for a purpose to be hereinafter more fully described.

The tube has a reduced section 5 con: nected with its lower end as clearly shown of Fulton and flanged collar is adapted to receive thereon an outwardly projecting angular spacing member 10 secured in the upper end of said reduced portion, and said flanges being resting upon each other and adapted to allow the lower reduced portion 5 to rotate thereon. The opening a'nd'lining through the floor of the car form a journal in which this reduced portion of the tube is adapted to rotate.

Extending longitudinally through. the

tubes 1 and 5 is an operating rod 11 which is supported in a spider structure 12 carried by the collar member 9 in the lower end of the tube 1, and on its upper portion positioned in the head 2 of said tube is formed an operating handle 13 that has connected therewith an enlarged disk 14 positioned on the rod 1, and having its outer edges adapted to rest upon the shoulders 4 of said head. The'disk 14: is provided with opposed depending lugs 15 adapted to drop into the notches in said shoulders to lock the rod in a certain position. The handle has a spring connection with the upper end 7 of the rod as clearly shown at 15 in Fig.

1 of the drawings for the purpose of which is obvious. The lower end of the rod 11 is connected with the lower end of the tube by an apertured diametrically extending member 16, that is secured in the lower end of 7 said tube.

This member is provided with a projecting enlarged portion 17 thereon that receives on 1ts outer end an enlarged lnlet head 18 which has its lower portion bent at right angles as shown at 19 and enlarged as at 20. The enlarged open end of the head has a projecting screen 21 positioned thereover to prevent cinders or dirt from being drawn up through the tube.

In operation, when this device is positioned on a railroad coach, the rotatable inlet head 18 is normally positioned in the 7 opposite direction from the motion of the As thls inlet is positioned adjacent car. the journal, and when it is desiredto test a journal of said car.

the same from the interior of the car the closure 3 is opened and the operator grasps the handle 13 and rotates the same to rotate the rod 11. This rotation of the rod 11 will turn the inlet head 18 so that it will be disposed in alinement with the motion and advantages of my invention may be had, 7

and While I have shown and described the device as embodying a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A device of the class'descri'bed includ- I ing in combination with arailway car, of a vertical tube carried thereby and positioned throu h the floor of said car, and a rotatable inlet for the lower end of said tube adapted to be moved in and out of position adjacent '2. A device of the class described including in combination with a railway car, a vertical tube carried thereby and positioned through the floor of said car, a rotatable inlet for the lower end of said tube, and means for rotating said inlet from the opposite end of the tube.

3. A'device of the class described including in combination with a rallwaycar, of a vertical tube carried thereby and positioned ture hereto.

through the floor of said car, an angular ing in combination with a railway car, a.

tubular member adapted to be ro-tatably mounted through the floor of the railway car, an angular inlet member connected with the lower end of said tube, said member having an enlarged outer end, a protective screening therefor, and means for rotating said member from the opposite end of the tube. 7

5. A device of the class described including in combination with a railway car, a tubular member adapted to be mounted in the side of the railway car, an extension on the lower end of said member rotatably mounted through the floor of said car, an angular inlet connected with the lower end of said extension, and a rotating rod extending through said tube and extension and connected with the inlet member. a

6. A device of the class described including in combination with arailway car, a tubularmember adapted to be positioned in the side of the railway car, an extension on the lower end thereof rotatably mounted through the floor of said car an angular inlet communicating with said extension and connected' with the lowerend'thereof', a rotatable operating rod extending through said tube and extension and connected with the inlet member, and means on the upper end ofsaid rod whereby the same is adapted to p be rotated, said means including a member to'hold the rod in fixed position.
